Bitcoin Cash (BCH)

Overview

Bitcoin Cash (BCH) is a cryptocurrency built for payments between people. Someone with a BCH wallet can send money directly to another wallet, without asking a bank to move it. Transactions are recorded on a public blockchain, and the network is maintained by computers around the world. Its main goal is to make digital payments practical for everyday use, including small purchases and transfers across borders. (coingecko.com)

Bitcoin Cash grew out of Bitcoin in 2017. The two networks share their early history and several core rules, but they have operated as separate blockchains since the split. BCH puts particular emphasis on making room for more transactions in each block. It has also added tools for creating tokens and building payment-related applications. (documentation.cash)

History & Team

The 2017 split

Bitcoin Cash began on August 1, 2017, during a debate over how Bitcoin should handle growing demand. One group favored increasing the amount of transaction data each block could hold. Other participants supported a different path for scaling Bitcoin. The disagreement led to a hard fork: a change in network rules that produced two independent chains. People who held Bitcoin at the split had a corresponding balance on the new Bitcoin Cash chain. (documentation.cash)

The launch was a group effort involving developers, miners, businesses, and users. Amaury Séchet led development of Bitcoin ABC, software that played a central role in the original fork. Roger Ver became a prominent advocate for BCH, while mining groups helped support the new network. Development later spread across independent teams. That history helps explain why changes to Bitcoin Cash require coordination among people running different software, rather than a decision by one company. (bitcoinabc.org)

Milestones since launch

Bitcoin Cash initially allowed blocks larger than Bitcoin’s original one-megabyte limit. A 2018 upgrade raised its block-size limit to 32 megabytes. Later upgrades introduced native CashTokens in 2023 and an adaptive block-size rule in 2024. Changes in 2025 expanded what its scripting system could calculate. The May 2026 upgrade added further tools for writing more capable on-chain programs. (upgradespecs.bitcoincashnode.org)

Technology & How It Works

Payments and mining

Bitcoin Cash uses proof of work. Miners gather transactions into blocks and compete to add those blocks to the chain. Other network computers check that the blocks follow the rules. A new block is targeted roughly every ten minutes on average. The network adjusts mining difficulty as computing power changes, helping it maintain that long-run target. Miners receive newly issued BCH and the fees attached to transactions they include. (documentation.cash)

A wallet creates a payment by signing a transaction with a private key. That signature shows the network that the sender can spend the BCH in question. The payment is then broadcast, checked, and placed in a block. Wallets can display a transaction before it receives a block confirmation; a confirmation arrives when the transaction is included in a mined block. (documentation.cash)

Block space and on-chain programs

Larger blocks give BCH room to place more payments directly on its blockchain. Since 2024, an adaptive algorithm has allowed the maximum block size to change gradually in response to block usage, with 32 megabytes as its starting floor. This approach aims to let capacity grow with demand instead of requiring a new fixed limit each time. The space a transaction uses, and the demand for that space, still affect the fee a sender pays. (upgradespecs.bitcoincashnode.org)

Bitcoin Cash also supports scripts: rules that say when funds may be spent. Developers can use them for arrangements more detailed than a simple payment, such as releasing funds only when stated conditions are met. CashScript provides a language and tools for building these contracts. The 2026 upgrade added bounded loops, reusable functions, bitwise operations, and a pay-to-script format. Together, these changes broaden the kinds of rules developers can express on the main chain. (cashscript.org)

Tokenomics & Utility

Supply and distribution

BCH follows the supply model it inherited from Bitcoin. Its maximum supply is 21 million coins, and one BCH can be divided into 100 million smaller units called satoshis. New coins enter circulation as part of the reward for mining a block. That reward began at 50 BCH and is cut in half every 210,000 blocks. Transaction fees provide miners with an additional source of payment. (coingecko.com)

The 2017 split shaped BCH’s initial distribution: holders of Bitcoin at the fork held matching coins on the Bitcoin Cash chain, provided they controlled access to those holdings. Coins issued afterward followed the mining rules. BCH now serves three connected purposes. People use it to make payments, miners receive it for adding valid blocks, and users spend small amounts of it on transaction fees. (bitcoinabc.org)

BCH and CashTokens

Applications can issue other assets on the Bitcoin Cash blockchain through CashTokens. These assets are distinct from BCH. CashTokens support both fungible units, which can be exchanged one for another within the same category, and non-fungible tokens, which can carry individual information. BCH remains the network’s native coin for payments and fees when those tokens move. (cashtokens.org)

Ecosystem & Use Cases

The simplest use is sending BCH between people. A customer can pay a merchant, a family member can transfer funds to someone abroad, or a reader can send a small tip. Low transaction fees make smaller payments more practical. Payment services also support merchant use: BitPay, for example, lists BCH among the currencies customers can use to pay supported invoices. Acceptance depends on the business and the payment methods it offers. (support.bitpay.com)

Developers use the same chain for projects involving tokens and contracts. A fungible CashToken might represent units used within an application, while a non-fungible one might serve as a ticket or a record with its own details. Contracts can set conditions for how funds or tokens move. These uses build on BCH’s payment system, though they call for different wallets and software than a basic transfer. (cashtokens.org)

The ecosystem includes optional wallet tools as well. CashFusion combines inputs and outputs from several participants into a shared transaction, making it harder to link each input to a particular output. It is an application people can choose to use, rather than a step built into every BCH payment. (cashfusion.org)

Advantages & Challenges

Bitcoin Cash’s main advantage is its direct approach to payment capacity. It has substantial room for transactions in each block, a familiar proof-of-work design, and a ten-minute average block target. Its supply rules are straightforward, and the same network can support both ordinary transfers and native tokens. Independent development teams can also work on different pieces of the system. (upgradespecs.bitcoincashnode.org)

Those design choices bring practical trade-offs. Larger blocks require more data to be sent, stored, and checked by computers that maintain the chain. An adaptive limit gives the network a way to respond to demand, while keeping software performance important as usage grows. Bitcoin Cash also competes for payment users, merchants, miners, and developers with other networks and established payment methods. Its technical capacity matters most when people and businesses choose to use it. (github.com)

Where to Buy & Wallets

Bitcoin Cash can be purchased on Coinbase and Kraken. Available payment methods and account features vary by location. After purchase, BCH can remain in an exchange account or be moved to a wallet controlled by its holder. (coinbase.com)

Electron Cash is a BCH wallet that lets users control their private keys and supports CashTokens. Trezor and Ledger offer hardware-wallet options for holding and managing BCH. A receiving wallet displays an address for the Bitcoin Cash network; the sender selects BCH when making the transfer. Different wallets offer different features, so basic payments and CashTokens may call for different software. (electroncash.org)

Regulatory & Compliance

Rules for using and providing services around BCH depend on the jurisdiction. In the United States, the Internal Revenue Service treats digital assets as property for federal tax purposes. Selling BCH, exchanging it for another asset, or spending it on goods or services can therefore have tax consequences. Businesses that exchange or transmit convertible virtual currency may also fall under FinCEN’s money-transmitter rules, depending on what they do. (irs.gov)

In the European Union, the Markets in Crypto-Assets regulation provides a framework for crypto-asset service providers, including firms offering exchange and custody services. In the United Kingdom, businesses providing services covered by the money-laundering regulations must register with the Financial Conduct Authority. These requirements concern the activities of service providers as well as the assets they handle. (esma.europa.eu)

Islamic Finance Guru assesses Bitcoin Cash as halal, reasoning that its basic role as a payment asset is similar to Bitcoin’s and is not tied by design to interest-based lending. Shariah judgments also depend on the principles applied to cryptocurrency and on how an asset is used. This makes the purpose and structure of a particular BCH transaction relevant to a religious assessment. (islamicfinanceguru.com)

Future Outlook

Bitcoin Cash’s path will depend on both its technology and its use in daily life. Its adaptive block-size rule provides a way for capacity to respond to sustained demand. CashTokens and the scripting changes completed through 2026 give developers more building blocks for wallets, payment services, and on-chain applications. Further improvements will depend on development, testing, and agreement among network participants. (upgradespecs.bitcoincashnode.org)

The central question is how often people will choose BCH for payments and whether businesses will make it convenient to accept. Tools for holding coins, paying invoices, and creating applications are already part of the ecosystem. Their usefulness will be measured by how well they meet needs outside the network itself.

Summary

Bitcoin Cash is a proof-of-work cryptocurrency focused on peer-to-peer payments. It began as a split from Bitcoin and developed its own rules for greater on-chain capacity, along with support for native tokens and more capable scripts. BCH’s place in the broader crypto ecosystem rests on a clear purpose: giving people a way to send and receive digital money directly. (documentation.cash)
